You may be interested in quantile regression. Roger Koenker, who has developed a lot of the basic methodology for quantile regression, is also the author of the quantreg package (which comes with a fairly thorough vignette IIRC). ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
